Answer from AI

GRASP (General Responsibility Assignment Software Patterns) is a set of principles for distributing responsibilities among classes and objects in object-oriented design. The main principles of GRASP help create more maintainable and understandable code. Among them:

  • Creator: a class that creates objects of another class should have a close relationship with them.
  • Information Expert: responsibility should be assigned to the class that has the necessary information.
  • Low Coupling: classes should be loosely coupled so that changes in one minimally affect others.
  • High Cohesion: a class should have a narrow and well-defined responsibility.
  • Controller: an object that handles system events and delegates tasks to other objects.

These principles help organize code to be more flexible and easier to maintain.
